BINDING STRIP.

Application filed January 15, 1926. Serial No. 81,409.

Thisinvention is an improvement in binding strips, and more particularly in bias cut fast-edged strips, of the character described and claimed in my prior Patent No. 1,457,- 625, June 5, 1923.-

In the better class of garments, the inside seams are piped, that is bound with edging strips. The edges of the strips are turned in. beneath the body on each side of the seam, so that the seam is covered and concealed.

In order to prevent puckering of the strips during the connection thereof with the garments, it is usual to cut the material on the bias, and so cut there is increased liability to ravelling at the edges.

In the prior patentabove mentioned, a method of remedying this trouble is set forth. This end is gained by treating the edges of the strip in such manner that the fibers of the threads are compacted together, and do not easily rave].

. A preferred method of preparing the strips is by cutting a wide piece of suitable fabric diagonally to form pieces of suitable length, and the selvage edges are sewed togetherto produce a wide strip in which the fabric threads run diagonal.

This widestrip is then rolled, and the roll is severed at regular intervals to produce individual rolls of the proper width, the strips in the rolls being relatively narrow. The edges of the strips, while still in the roll are treated with the material which compacts the fibers. i

It has been found in practice that any material suitable for use in treating the edges of the fabric strips, that is a substance containing one or more of the carbohydrate group, has in common with the members of the group an attraction for moths, and if the garment is in condition conducive to moth visitation, larvae are prone to develop in the piped seams, and to mar the sightly appearance of the piping.

One of the primary objects of the present invention is the provision of a method of treating the material with which the strips are fast edged in such manner that moths and moth larvae will be deterred from feed ing thereon.

Another object is the provision of a bias cut strip, having a fast edge which will not ravel, and treated with a substance poisonous to moths and moth larvae, thereby to prevent moth ravages. 7

Another object is the provision of a strip of the character in question, wherein the limits of the treated edge are distinguished from the remainder of the strip, by means of a pigment incorporated in the sub tance with which the edges are treated.

Another ohicct is the provision of a strip wherein the character and class of the material may be determined by the treated edges. With these and other objects in view the invention consists in the construction and novel combination of parts fully described hereinafter. illustrated in the accompanying drawings, and pointed out in the claims ap pended hereto. it bein nderstood that vari-- ous chanrres in the form, proportion. size and minor details of construction within the scope of the claims, may be resorted to without departing from the spirit of the invention.

In the drawing:

Fir. 1 is a perspective view of a roll of the improved strip, with a part unrolled.

Fig. 2 is a plan view of a part of the strip.

The improved strip 1 forming the subject matter of the present invention is usually bias cut, in order to prevent puckerine when the strip is applied tothe garment in the form of piping. In preparing the strip, bias cut pieces are connec ed end to end by the selvage edges, andthe piece soformed is rolled, usually on a suitable core 2.

A rol so formed is cut into individual strip and the edges 3 of the strips in the rolls are treated with the fast edging-1' material. The material used must have certain characteristics. but any material having such characteristics may be used. For instance the material must be dry and solid at normal temperatures. It must be capable of cementing the fibers of the threads together, and it must have a degree of elasticity in order that it will not break and be dislodged during the handling of the strip.

The material should. also be insoluble in water, and a hard resin of an elastic charac ter such for instance as copal is very suitable for the purpose. Hard resins are dry rolls, each'composed of relatively narrow by dry heat.

and solid at normal temperatures, and they maybe applied in emulsion in a volatile indicated by the color of the pigment.

As for instance satin may be. represented by one color, silk by another, and in like manner. Thus at a: glance the user may determine, first that the strip has been'pr'o'perly treated to fast edge and moth proof, the same, and second thatthe strip is of the material which he desires to use in the garment, without the necessity of releasing the strip,

or unwinding any part thereof.

While ive have described the stripes a bias cut strip, it is obvious that the treatment with the fast edging material, the 'moth roofin substance and the Ji 'ment is e ually applicable to strips not cut on the bias.

In fact the treatment may be applied to ad not provided vantage on any textile strip with a selvage edge. I

Any suitable material or substance may be used'wliich will serve as an alimentary poison or a deterrent'to feeding of the moths V and moth larvae, as for instance the soluble or insoluble arsenic preparations, such as calcium arsenate, sodium arsenate and the like. Other suitable materials are the fluorides such as zinc and sodium fluoride. The latter class of chemicals'whi'ch while poisonous to moth and moth larva: are relatively innocuous to vertebrates, are very suitable for the purpose.

There can be no danger however from even the more active poisons, such as sodium arsenate. Very slight handling of the strip is necessary'at any time.

The strips are f usually applied by a sewing maehine,and the port-ion of the'strip and the garment, so that no part of the treated strip is exposed. Furthermore the amount needed to thoroughly moth proof is so small in any reasonable area as to be substantially without danger;

While We have referred to theinothproofedges are inturned between the untreated ing of the strip as only'at the edges, it will be obvious that 'the entire strip might be mothproofed, that is the portion between the (3(5lGS Gltl10ll prior to the treatment for fast edging or afterwards.

We claim: p p 1. A. bias cut binding strip having the fibers at the edges thereof cemented together.

by a substance havingincorporated therein an alimentary poisonfon noths and, moth larvae, and including'a pigment to distinctively color the cementededges;
